Straight answers.

How much does an app cost?

Mobile apps start from £4,500. You get a fixed quote after a free 30-minute audit call, once the first release is agreed.

Do you build native apps or cross-platform apps?

Both. React Native + Expo is often the best route for speed, while SwiftUI is a strong fit for privacy-first Apple-only products.

Can you help with App Store submission?

Yes. Screenshots, metadata, privacy notes, subscriptions, TestFlight, and review fixes can all be part of the project.

What happens after launch?

Launch is the start. Claude can be set up to watch reviews, crashes, numbers and your store listing, and to draft release notes and posts. You approve what goes out. See AI business setup.

Can the app connect to AI or automation?

Yes. Football IQ already uses an AI content pipeline, and apps can connect to Supabase, serverless jobs, n8n workflows, or custom APIs.

What should I bring to the first call?

A rough app idea is enough. The useful first step is deciding the smallest loop that proves the product should exist.

Got an app idea that keeps coming back?

We can turn it into the smallest useful version and find out whether it has legs.
